Description

Technical Field

[0002] Cameras are devices used to capture images or videos. They are widely used in various fields to help record, monitor and analyze environments, objects or activities. In forestry surveys, cameras usually refer to special equipment used to collect data on forest ecology, vegetation distribution, species observation, etc.

[0003] For example, a Chinese utility model patent (CN210761315U) discloses a photographing device for forestry investigation and its buffer mechanism and protective device, which records: "The buffer mechanism can play a buffering role when the photographing device hits the ground, thereby preventing the photographing device from being damaged by excessive impact force. The protective device can cover the photographing lens when the photographing device is not in use, thereby providing a certain degree of protection for the photographing lens." It also records: "When the existing photographing device for forestry investigation hits the ground during use, the impact force is too large, which can easily damage the photographing device and cannot provide a certain degree of protection for the photographing lens." Technical problems.

[0004] In summary, it can be seen that the prior art uses drones for filming, but this method has the following technical problems: after the actual forestry survey and filming is completed, there may be a lot of weeds growing at the location where the drone lands after the filming is completed. During the landing process, the weeds may be drawn into the propeller of the drone, causing damage to or obstruction of the propeller. For this reason, the present application proposes a buffer mechanism and a protective device for a filming device, which provides a new technical solution to solve the technical problems mentioned in the above patents. Summary of the invention

[0005] Based on this, it is necessary to provide a buffer mechanism and a protective device for a filming device in response to the above technical problems. The device is moved to the ground at the designated location where the filming drone is to land, and then the two U-shaped handles are pressed downward at the same time, so that the earth-breaking cone can be inserted into the ground, and then the two pull rods are pulled until the front-to-back parts are in contact with the U-shaped handles. At this time, the T-shaped plug leaves the corresponding sliding rod, and then the left and right sets of U-shaped handles and the pull rods are held and lifted upward, which can drive the device housing to rise accordingly, so that the distance between the device housing and the connecting frame changes accordingly. After reaching the appropriate position, the two pull rods are released, so that the T-shaped plug is inserted into the corresponding second spring force. The soil-breaking cone can be inserted into the corresponding hole on the sliding rod, and the stability of the installation and placement of the device is improved by inserting the soil-breaking cone into the ground. The height of the landing net can be adjusted accordingly by adjusting the distance between the device shell and the connecting frame. The height of the landing net is adjusted to the height of the weeds nearby to reduce the possibility that the tips of higher weeds swing above the landing net, thereby affecting the landing of the drone, and reducing the situation where the weeds are caught in the propeller of the drone and cause damage to the drone, thereby improving the protection effect of the drone shooting device and the practicability of the device, and by shortening the distance between the device shell and the connecting frame, the space occupied by the device when not in use can be reduced, thereby improving the portability of the device.

In addition, by shortening the distance between the device shell 1 and the connecting frame 11, the space occupied by the device when not in use can be reduced, thereby improving the portability of the device.

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

The device can be stably installed on the ground through the installation assembly.

[0029] The pulling assembly includes a T-shaped plug block 13, and the inner wall of the device housing 1 and near the front and rear sides are slidably connected with the T-shaped plug block 13, the T-shaped plug block 13 is movably inserted in the sliding rod 10, the T-shaped plug block 13 is slidably connected to the inner wall of the U-shaped handle 9, a pull rod 15 is fixedly connected between the two T-shaped plug blocks 13, the pull rod 15 is slidably connected to the inner wall of the U-shaped handle 9, and a second spring 14 is fixedly connected to the side of the T-shaped plug block 13 away from the device housing 1, and the end of the second spring 14 away from the T-shaped plug block 13 is fixedly connected to the inner wall of the U-shaped handle 9. By pulling the front-to-back portion of the pull rod 15 until it fits with the U-shaped handle 9, the restriction on the sliding rod 10 can be released, and then the distance between the bottom of the device housing 1 and the top of the connecting frame 11 can be adjusted, and then the pull rod 15 can be released to limit the distance between the device housing 1 and the connecting frame 11.

[0030] Through the above structural design, by moving the device to the ground at the designated location for shooting the drone landing, and then pressing down the two U-shaped handles 9 at the same time, the earth-breaking cone 12 can be inserted into the ground, and then the two pull rods 15 are pulled until the front-to-back portion fits with the U-shaped handle 9, at this time the T-shaped plug 13 leaves the corresponding sliding rod 10 and slides toward the inside of the U-shaped handle 9, thereby causing the corresponding second spring 14 to deform, and then the left and right sets of U-shaped handles 9 and the pull rod 15 are held and lifted upward, the device housing 1 can be driven to rise accordingly, so that the distance between the device housing 1 and the connecting frame 11 changes accordingly, until the top of the landing net plate 3 is higher than the surrounding grass and trees that may affect the drone, and then the two pull rods 15 are released, so that the T-shaped plug 13 is inserted into the corresponding hole on the sliding rod 10 under the action of the elastic force of the corresponding second spring 14, and the installation adjustment of the device can be completed. When the drone needs to land after completing the shooting, the drone can be controlled to land on the landing net plate 3.

[0031] Embodiment 2: The buffer mechanism and protective device for the shooting device provided in Example 1 are further optimized. Specifically, Figure 5-Figure 6 As shown, the rotating assembly includes a first fan blade 18, and the tops of the two rotating rods 17 are fixedly connected to the first fan blade 18. The inner wall of the fixed box 16 is fixedly installed with a spring 19, and the spring 19 is fixedly connected to the outer wall of the rotating rod 17. The rotating assembly can rotate due to the air flow driven when the drone is suspended above the landing net 3, and store this part of the force.

[0032] The transmission assembly includes a first bevel gear 20, and the outer walls of the two rotating rods 17 are fixedly connected to the first bevel gear 20. The inner wall of the device housing 1 is rotatably connected to two transmission rods 21. One end of the two transmission rods 21 located inside the device housing 1 is fixedly connected to the second bevel gear 22. The second bevel gear 22 is meshed with the outside of the first bevel gear 20. The transmission assembly can drive the subsequent rotating rod 26 to rotate as the rotating rod 17 rotates, thereby causing the second fan blade 28 to rotate and drive air flow.

[0033] The blowing assembly includes a wind tube 24, the outer wall of the device housing 1 is fixedly connected to the wind tube 24, the transmission rod 21 is rotatably connected to the inner wall of the wind tube 24, one end of the two transmission rods 21 located inside the wind tube 24 is fixedly connected to the third bevel gear 23, the inner wall of the wind tube 24 is rotatably connected to two rotating rods 26, the tops of the two rotating rods 26 are fixedly connected to the second fan blades 28, the bottoms of the two rotating rods 26 are fixedly connected to the fourth bevel gear 27, the fourth bevel gear 27 is meshed with the outside of the third bevel gear 23, the bottom of the wind tube 24 is detachably connected to the dustproof net 25 by bolts, the rotation of the second fan blades 28 in the blowing assembly can drive the external air to pass through the dustproof net 25 into the wind tube 24, and finally blow toward the camera of the drone through the wind tube 24.

[0034] Through the above structural design, when the drone is suspended on the top of the landing net plate 3 and is ready to fall, the rotation of the propeller on the drone can drive the surrounding air to flow, and the flowing air passing through the landing net plate 3 can affect the two first blades 18, thereby causing the two rotating rods 17 to rotate accordingly, thereby causing the spring 19 to deform and store power. After the drone camera falls onto the landing net plate 3 toward the position of the wind tube 24, the propeller on the drone is turned off, and then the spring 19 begins to release the elastic force, thereby driving the rotating rod 17 to rotate, and then passing through the first The first bevel gear 20 and the second bevel gear 22 drive the transmission rod 21 to rotate, and then the transmission rod 21 drives the rotating rod 26 to rotate through the third bevel gear 23 and the fourth bevel gear 27, and finally the corresponding second fan blade 28 can rotate, which can drive the outside air to flow into the wind tube 24 through the dustproof net 25, and finally make the wind tube 24 blow air to the camera on the drone, so as to clean the dust, sand, soil or water droplets that the camera on the drone contacts during the flight, so as to prevent them from accumulating on the lens and affecting the shooting quality.

[0035] Embodiment 2: The buffer mechanism and protective device for the shooting device provided in Example 1 are further optimized. Specifically, Figure 7-Figure 9As shown, the extension component includes a hemispherical plug block 31, the inner wall of the extension rod 30 is slidably connected with the hemispherical plug block 31, and the side of the hemispherical plug block 31 located inside the extension rod 30 is fixedly connected with a third spring 32, and the end of the third spring 32 away from the hemispherical plug block 31 is fixedly connected to the inner wall of the extension rod 30, and two sockets 33 are provided on the sleeve 29, and the hemispherical plug block 31 is movably inserted in the sockets 33. By clamping the hemispherical plug block 31 in the extension component in the socket 33 near the top of the sleeve 29, the extension rod 30 can be maintained at the current position relative to the sleeve 29, thereby extending the overall length of the sleeve 29 and the extension rod 30.

[0036] The wind shield assembly includes a threaded rod 34 and a wind blocking net 38. The top of the extension rod 30 is threadedly connected to the threaded rod 34, and the top of the threaded rod 34 is fixedly connected to the squeezing handle 35. The outside of the four sleeves 29 is sleeved with a limiting sleeve 36, and the inner walls of the four limiting sleeves 36 are fixedly connected to a plurality of pressing plates 37. The wind blocking net 38 is fixedly connected to the outer walls of two adjacent limiting sleeves 36. The overall length of the limiting sleeve 36 and the wind blocking net 38 is long enough to be installed between the squeezing handle 35 and the extension rod 30 when the pressing plate 37 is installed. When the sleeve 29 and the extension rod 30 are extended, the bottom edges of the limiting sleeve 36 and the wind blocking net 38 naturally hang down and contact the top of the landing net 3. The wind blocking net 38 surrounds the air in the external environment and slows down the flow rate after it blows to the top of the landing net 3, so as to reduce the interference of the external environment on the drone.

[0037] Through the above structural design, by installing the four sleeves 29 one by one at the appropriate positions on the landing net 3, the limiting sleeves 36 are then set on the outside of the sleeves 29 one by one, and then the pressing sheet 37 is placed between the top of the socket 33 and the bottom of the squeezing handle 35, and then the threaded rod 34 is tightened, so that the squeezing handle 35 and the socket 33 can squeeze and restrict the pressing sheet 37, and the installation of the limiting sleeve 36 and the wind-blocking net 38 can be completed. Then, the extension rod 30 can be pulled so that the inner wall of the sleeve 29 squeezes the hemispherical plug 31, so that the hemispherical plug 31 slides toward the inner part of the extension rod 30, and then the third spring 32 is deformed. As the extension rod 30 is pulled, the hemispherical plug 31 can be stuck in the upper socket 33, and the overall length of the sleeve 29 and the extension rod 30 can be extended, and the limiting sleeve 36 and the wind-blocking net 38 can be further expanded, so that the wind can be blocked for a wider range of the landing of the drone, and the wind speed above the landing net 3 is reduced.
